bination and arrangement of parts through the medium of which the air may be filtered and 1 humidified simultaneously.

Other objects of the invention are to provide an air conditioning device of the aforementioned 'character'which' will be comparatively simple in construction, strong, durable, highly eflicient andv 15. reliable in operation, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specifica- 2d tion, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:- Figure 1 is a view in side elevation of an air '25 conditioning device constructed in accordance with the present invention.

Figure 2 is a view in top plan thereof. Figure 3 is a vertical sectional view,.taken substantiallyon the line 3-3 of Flgure'l;

Figure 4 is a view in vertical longitudinal section through the device.

Figure 5 is a view in vertical transverse section, taken substantially on the line 5--5 of Figure 4. Figure 6 is a view showing the device installed for operation in the air intake of a hot air furnace. Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a pair of channel-shaped side members 1 on the ends of which containers 2 are provided, said containers 2 being for the reception of water to a predetermined level, as indicated at 3.

Mounted on the side members 1 and extending between the containers 2.are guides 4 which include hinged upper portions 5. Rollers 6 are journaled transversely in the containers 2 above the level of the water 3 and running over said .rollers 6 is an endless filtering and humidifying web 7 of suitable fabric of the desired mesh. Also journaled in the containers 2 below the level of the water 3 are comparatively large rollers 8 and 9 under which the web 7 travels, the elements 8 and 9 thus constituting immersion rollers. The end portions of the rollers 6, 8 and 9 are grooved for the reception of endless rubber belts 10 of substantially circular cross-section which are se-' cured by suitable means, preferably by vulcanizing, on the marginal portions of the web 7.- ,The belts 10 travel in the guides 4 between the con-- tainers 2. The reference numeral 11 designates screens which are mounted between the upper and lower guides 4 for supporting the upper and lower flights of the web 7 between the containers 2. For drainage purposes, the containers 2 are provided with petcocks 12. 7

As best seen in Figure 3 of the drawings, th roller 9 is connected with a shaft 13 which is journaled in the upper portion ofthe respective container 2 above the level of the 'water 3 therein by a belt and pulley connection 14. The shaft 13 is operatively connected to an electric'motor 15 by a belt, pulley and gear connection which is designated by the reference numeral 16 and which is shown to advantage in Figure 6 of the drawings.

It will be noted that the. connection 16 comprises 76 change speed pulleys which permit the web 7 to be driven at various speeds. It will thus be seen that the roller 9 constitutes a live or drive roller.

As illustrated to advantage in Figure 6 of the drawings, the embodiment of the apparatus so shown may, for example, be mounted in the air intake casing 17 of a furnace in such a manner that air is drawn downwardly therethrough by the fan, as indicated by' the arrows. When this arrangement isutilized the furnace fan is also driven by the electric motor 15. As is believed to be apparent, the air will be thoroughly filtered and humidified as it passes through the upper and lower flights of the web 7. It may be well to here mention that the web 7 is of highly absorbent material for picking up the water in the containers 2 as it passes beneath the rollers 8 and 9. The hinged upper sections 5 of the guides 4 facilitate removal and renewal of the web 7 with the belts 10 thereon when desirable or necessary.

It is believed that the many advantages of an air conditioning device constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the invention is as illustrated and. described, it

bers, guides mounted on the side members and extending between the containers, rollers journaled in the containers, certain of said rollers being submerged in the Water, said rollers having grooves in their end portions, an endless web of absorbent fabric trained over the rollers and operable in the guides, endless belts of substantially circular cross section on the marginal portions of the web, said belts being operable in the guides and engageable in the grooves of the rollers, means operatively connected with one of said rollers for actuating the web and means for passing air through the said web.

2. An air conditioning device of the class described comprising a pair of side members, water containers mounted on the ends of the side members, rollers journaled in thecontainers, certain the rollers for actuating the web. screens mounted between the guides for supporting the upper and lower flights of the web between the containers and 'means for passing air through the said web.
